Stable immobilization of two redox proteins, cytochrome c and azurin, in a thin film of highly mesoporous antimony-doped tin oxide is demonstrated via UV-vis spectroscopic and electrochemical investigation.

For atomic layer deposition (ALD) of doped, ternary, and quaternary materials achieved by combining multiple binary ALD processes, it is often difficult to correlate the material properties and growth characteristics with the process parameters due to a limited understanding of the underlying surface chemistry. In this work, in situ Fourier transform infrared (FTIR) spectroscopy was employed du...

The present review deals with the recent progress made in field of electrochemical detection serotonin by means sensors based on various nanomaterials incorporated sensitive element. Due to unique chemical and physical properties these nanomaterials, it was possible develop excellent analytical performances, useful practice. main used are carbon electrodes modified nanotubes materials, such as ...

Optically-based lab-on-a-chip systems have the distinct advantage of being dynamically controlled in real time, providing reconfigurable operations that can be tuned to perform a variety of tasks. This manuscript demonstrates the concentration of liquid-suspended microparticles using a focused near-infrared laser (980 nm) and a parallel-plate electrode system. The parallel-plate electrodes cons...

The synthesis feasibility of silicon-tin nanocrystals by discharges in liquid nitrogen is studied using a Si-10 at % Sn sintered electrode. Time-resolved optical emission spectroscopy shows that silicon and tin melt almost simultaneously. The presence of both vapours does not lead to the synthesis of alloyed nanocrystals but to the synthesis of separate nanocrystals of silicon and tin with aver...

Tin oxide films were implanted with N at various energies between 5 to 40 keV for different ion doses between 10 to 10 cm. The microstructure, optical and electrical properties of the films were investigated. From Transmission Electron Microscopy the implanted films were shown to be amorphous. The implanted thickness for the 10 keV and 40 keV were found to be 30 nm and 110 nm, respectively. The...

A low level tin doped indium oxide, ITO, (ca. 10 w % SnO2) thin films were prepared on glass substrate by electron beam technique. Deposited films with deposition rate of 0.1–0.25 nm s were annealed at different temperatures from 250 to 550 °C in air. The thin films were characterized using low and high angle X-ray diffraction and UV-visible spectroscopy. The lattice constant and the grain size...

Tin-doped indium hydroxide (InSnOH) nanowires (NWs) and nanotubes (NTs) were grown from acidic aqueous solutions of inorganic precursors in a simple one-step electrochemically assisted deposition (EAD) process inside Au-plugged anodic aluminium oxide and polycarbonate membranes. When the membranes were used without any pre-treatment, InSnOH crystals nucleated on the both the Au-cathode and pore...

Optical modeling was applied for obtaining absorbance spectra and band gap values for different morphology of ZnO semiconductor. In optical modeling, the relative permittivity scalars of zinc oxide coral like nanorods were calculated using the Bruggeman homogenization formalism. ZnO nano rods (ZONRs) as a nucleus layer were fabricated on the Indium Tin Oxide (ITO) by chronoamperometry (CA) in a...
